Joe Jonas Talks Demi Lovato, Ashley Greene and Those Gay Rumors...

Does Demi Lovato have to worry that she's the subject of a song on Joe Jonas' new solo album? How about his other former girlfriend Camilla Belle? Or Taylor Swift, who was so bitter about her split with the JoBro's she wrote "Forever & Always" about him?

"I think all artists have a right to write about what happens to them," Jonas says in the new issue of Details magazine. "But I have a right to write about things too."

It was about two years ago, and the gal was someone in the entertainment biz. "I won't say her name," he says. "But I was in a relationship, and we tried to work things out, and she, you know—I was really upset because she—she broke up with me."

Things are going much better with his current lady love, Twilight star Ashley Greene. "I think what works about it is she really puts my feelings first," he says. "She understands my busy schedule. She'll fly out to my shows—she's been to places in South America that I can't even pronounce."

And as everyone knows, it was a stop in South America when all that Lovato drama happened. "I wish her the best," is all Jonas will say about the incident.

Now about the ongoing gay rumors. "There's nothing wrong with being gay," he says, "but I'm not."

But he loves a gay guy with a sense of humor. "I like to watch all the crazy characters in the neighborhood," he says of living in a more commercial area of Hollywood. "I saw this gay homeless guy that got arrested. When the cops said, 'Spread 'em,' he was like, 'You'd like that, wouldn't you?'"

PS: We think you'll agree that plenty of women and gay men will surely appreciate the photos of Jonas in the magazine. Boy, his biceps are big.
